CHAIR-SEAT AND FABRIC THEREFOR.

SPECIFICATION forming part of Letters Patent No. 558,511, dated April21, 1896. l Application filed October 26, 1895. Serial No. 567,032. (Nomodel.)

To @ZZ whom t may concern.'

Beit known that I, EDMUND MORRIS, a citizen of the United States,residing in Michigan City, in the county of Laporte and State ofIndiana, have invented certain new and useful Improvements in Chair-Seats and Fabrics Therefor, of which the following is a specification.

Open-mesh cane-cloth has heretofore been extensively used forchair-seats and has fulfilled many of the requirements for such seats,affording the requisite ventilation, economy of material, and areasonable degree of strength and durability.

The object of my invention is to render such chair-seats stronger andmore durable. These ends I accomplish by forming the fabric whichconstitutes the body of the seat partly of open-mesh material and partlyof a close-woven material. The open-mesh material is that ordinarilyemployed for chair-- seats.

The close-woven material is woven into the open-mesh material and isarranged in one or more strips from front to back of the chair-seatframe.

My improvements are shown in the accompanying drawings, in which- Figurel shows a top plan view of a chairseat constructed in accordance with myinvention. Fig. 2 shows a bottom plan view of the same; and Fig. 3 is adetail View showing, on an enlarged scale, a crosssection of a portionof the fabric.

The body A of the chair-seat is formed of strips of cane or rataninterwoven to form a fabric and secured in a frame B in any suitableway, such as by splines b.

The drawings show the body as consisting of four strips C of open meshfabric and three strips D of close-woven fabric. The strips C consist ofwarp and weft threads arranged in pairs and interwoven as usual anddiagonals disposed in the usual way. The strips D are composed of warpand weft threads, but the warps are arranged close together withoutintervening meshes, and the diagonals are not interwoven, but extendacross the under side of the strips, as shown in Fig. 2. By thisconstruction there is more economy in material than where a close-wovenfabric is employed for the entire seat, and there 1s greater strengththan where an openmesh fabric is employed for the entire seat. Thestrips D extend from front to back of the chair and act as braces totake the strain of the weight, which, as is well known, is exerted to agreater extent at the front and rear edges of the fabric than anywhereelse. A single central strip D might be employed with good results, butI have shown three strips, as greater strength and durability isattained thereby. The diagonals E, crossing each other and extendingbeneath the strengthening-strips D, of close-woven material, serve asadditional supports therefor, and serve todistribute the strain orweight diagonally to other portions of the fabric.

My invention comprehends not only the combination of the improved fabricwith a frame for supporting'it, but the fabric itself, which, however,is especially adaptedfor being worked up into chair-seats.

I claim as my inventionl. A chair-seat fabric composed of strips ofopen-mesh cane-cloth comprising warp and weft threads arranged at rightangles and diagonal threads interwoven with the warp and weft threadsand arranged at right angles with each other, and one or more stripscomposed of warp-threads and weft-threads closely woven without meshes,and arranged above the diagonals extending from the openmesh strips. v

2. The combination of the chair-seat frame and the cane-cloth securedthereto around its edges, said cane-cloth having strips of openmeshmaterial comprising warp and weft threads arranged at right anglesand'diagonal threads interwoven with the warp and weft threads andarranged atright angles with each other, and one or more strips composedof warp-threads and weft-threads closelywoven without meshes andarranged above the diag onals extending from the open-mesh strips, saidstrips of close-woven material extending from front to rear of theseat-frame, substantially as described.

In testimony whereof I have hereunto subscribed my name.

EDMUND MORRIS.
